Adam, I am trying to root some cuttings of a variety of Morus nigra right now. The person I got them from said the fruit was truly fantastic and the tree is different than the usual black/Persian mulberries, it has a semi-weeping habit where it grows down and then back up. If they take I have one with your name on it. I also am growing Illinois Everbearing and Pakistan. The Illinois Everbearing is fruiting itself senseless right now, the fruit are smaller but tasty.
